WARNING
An open rear window or tailgate pro‐
trudes from the vehicle and can endanger oc‐
cupants and other traffic participants or dam‐
age the vehicle in the event of an accident,
braking or evasive maneuvers. In addition, ex‐
haust fumes may enter the vehicle interior.
There is risk of injuries or risk of property dam‐
age. Do not drive with the rear window or tail‐
gate open.◀
If driving with the tailgate open cannot be
avoided:
▷ Close all windows and the glass sunroof.
▷ Greatly increase the air flow from the vents.
▷ Drive moderately.
Hot exhaust system
WARNING
During driving operation, high tempera‐
tures can occur underneath the body, for ex‐
ample caused by the exhaust gas system. If
combustible materials, such as leaves or grass,
come in contact with hot parts of the exhaust
gas system, these materials can ignite. There
is risk of injuries or risk of property damage.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts in driving opera‐
tion, idle or during parking. Do not touch the
hot exhaust system.◀

Mobile communication devices in the
vehicle
WARNING
Vehicle electronics and mobile phones
can influence one another. There is radiation
due to the send operations of mobile phones.
There is risk of injuries or risk of property dam‐
age. If possible, in the car's interior use only
mobile phones with direct connections to an
exterior antenna in order to exclude mutual
disturbance and deflect the radiation from the
car's interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.

Driving through water

CAUTION
When driving too quickly through too
deep water, water can enter into the engine
compartment, the electrical system or the
transmission. There is risk of property damage.
When driving through water, do not exceed the
maximum indicated water level and the maxi‐
mum speed for driving through water.◀
When driving through water, observe the fol‐
lowing:
